Destroy 15 cursed jars in a single game. (Campaign, Survival)
This achievement requires that you destroy 15 cursed jars in a single game and can be done in either Campaign of Survival mode. Cursed jars are the containers that have purple smoke coming out of them. A worker will carry them along the path to the top of the tower and drop them. Destroying a cursed jar will temporarily disable the power used for a bit. As the jar-bearing worker spawns, they will let out an evil laugh to let you know.
You can obtain this in the first Survival level, Great Ziggurat Divinity. Play as normal, but instead of trying to avoid cursed jars, make sure to destroy them. In Campaign, cursed jars only spawn from Mission VII onwards, so be sure to chose that mission or a later one.
